ok, i finally saw this, and I really liked it. I think older people who see this won't like it because it isn't like many of the other Bonds. This one gives Bond a much more emotional side, he has problems and has to cope and deal with them. I never saw Casino Royale, but aren't these movies supposed to be taking place at the very start of his career? If that's the case, then it somewhat makes sense that he doesn't have a watch that does everything or a car with useless abilities, that by some miracle turn out to save him.
The plot i thought was not too bond like, why would MI6 care that much about the water prices in Bolivia? But of course that just ties in with the whole organization that we know nothing about (thought it seems Bond does at the end) and should make for a good sequel. While I miss the supervillians, I kind of like this type of plot more because it's real. No one is going to blow up the earth while they escape on space shuttles or anything like that. And there is no henchman who can chew through metal. It's quite realisitic.
I also agree with whoever said it, how bond now must answer to his seemingly random killing because he's killing possible leads. Overall, I'd say this is definitely worth seeing, but if you're expecting an old style Bond, with tons of gadgets, sweet cars, a lot of sex, and a ridiculous plot, then you'll hate it.
(oh, and people complain that he never does or says some things, like "bond, james bond" or his whole martini shaken not stirred thing....remember, there are other "classic" bond movies when he never does those things either)
